Making slider of count a parameter

Hi Everyone,

Any ideas on how I can use count of a certain paramter say 'x' as a slider. So far I have tried making it a measure but slider does not apply on it and I created a column which contained value '1' or '0' depending on whether the column has 'x'  but the slider obtaind from it only ranges from 0 to 1. I want to achieve what-if analysis scenario from it, so any other approach is also welcome.
